# Designing Data-Intensive Applications Skill

Use this skill when a task involves data ownership, consistency semantics, event flows, replication, partitioning, transactions, streams, batch processing, fault tolerance, or schema evolution.

Before making design or code decisions, read and apply [designing-data-intensive-applications.mini.md](designing-data-intensive-applications.mini.md). Use [designing-data-intensive-applications.md](designing-data-intensive-applications.md) only as a deeper reference when the mini rules are not enough for the current data-system tradeoff.
